▼ With mobile phones almost being ubiquitous in most communities, the electronic payment industry has realised the potential of using mobile phones as devices that can be used to conduct electronic payments. This realisation has led to an increase in the number of mobile payment solutions, which are being deployed for use by the public. However, these mobile payment solutions have not been widely adopted, especially by the citizens who are residing in the townships. Thus, this study investigates the factors that inhibit township residents from adopting mobile payments. The study was done at the Soshanguve township on the outskirts of Pretoria in Gauteng, South Africa. The study adopted a mixed method approach to collect data. Phase 1 relied on the interviews from a few selected individuals to collect the initial data, once this process was complete; a questionnaire (Phase 2) was developed and distributed to the general community of Soshanguve for
data collection, which was qualitatively and quantitatively analysed.the diffusion and use of mobile payments in the townships. Some of the factors are as follows: mobile payments are not easy to use; lack of products to purchase using mobile payments; high costs associated with using mobile payment solutions; lack of trialability of mobile payment solutions; and lack of awareness of mobile payment providers in the townships. The study proposes several guidelines that could help developers and operators of mobile payment solutions to design and deploy their solutions in such a way that they are suitable for consumption by the users in township communities. Proposed guidelines are as follows: (1) when a mobile payment solution is launched, effort should be made to market it to the target market; (2) potential adopters of mobile payments should be able to try it without incurring any financial penalties; (3) mobile payments should be easier to use; (4) mobile payment security features
should be apparent to the potential adopters in order to alleviate their fears; (5) mobile payment solutions should be designed according to the needs of the target market as one size fits all does not work; (6) mobile payment solutions should fulfill a need which is not met by the current alternatives or it should offer more value than the existing alternatives; (7) the cost of conducting mobile payments should be affordable; and (8) the regulator should develop legislation that stimulates innovation and competition while ensuring the security of mobile payments.

▼ Along with the emerging mobile telecommunicationãtechnology, mobile telecommunication industry has developed the different service from the traditional pronunciation communication. Applications of multimedia, data transmission and so on have changed people's life greatly.
For consumer, the mobile phone is not only the telephone conversation machine, but also is one kind of drawing close to life tool, the status symbol. The demand of mobile device has transforms from the traditional functionality demand into the psychological stratification.
They starts to care about what service the small mobile device serve. The border of telecommunication industry is also getting more and fuzzier. The 3G development is not into the expectation, the reason lacks the innovation application. But the software service has brings a revolution to the mobile telecommunication industry.
This research is for the purpose of discussing how mobile service enterprise plans the suitable transport business pattern based on the user attitude.
Base on the mobile portal, discusses the consumer to choose mobile service which factors to come under these factor influence and compared with two different case consumer's value localization..
The research result indicated that mobile service is restricted in mobile device the hardware characteristic and technology, but how to utilize innovates technology to promote attracts consumer's service, can be carries out mobile service the main consideration.
By the software develops platform, not only the third party software developers cut the product price, also, because the platform has discussion's space, enables the consumer to be possible to talk directly with the developers and improve the software use greatly then easy.

▼Mobile payment is an application of mobile commerce which provides the user with an ability to pay for goods and services using their mobile device. It is a payment mechanism that gives the consumer an ‘anytime anywhere’ freedom to perform a transaction. The purpose of this exploratory study is to understand what factors inhibit or facilitate adoption of mobile payment, in a New Zealand context. To study the potential links between these factors and mobile payment adoption a hybrid of two adoption models (the Technology Acceptance Model – TAM, and the Input Output Process model – IPO) were used to build the research framework. A corresponding questionnaire was designed and data were gathered from a total of 267 respondents. The findings about ‘control relationships’ such as between perceived ease of use and perceived usefulness, or perceived usefulness, perceived ease of use, and intention to use were compliant with prior work. The study identified service awareness as an important factor affecting the adoption of mobile payment. It was also found that consumer demographic characteristics such as income, professional status, ethnicity, and mobile phone spending may play significant moderating roles. The study contributes to the understanding of the dynamics of mobile payment adoption in the local context, and identifies avenues for future work in the area.

▼ Smart mobile devices have increasingly become the
computing platform of choice. As distinct features, they have
sensors and many useful applications based on the sensors have been
developed and are being widely used. Not surprisingly, many of
these applications rely on the cloud because of the resource
constraints inherent to mobile devices. ❧ In this dissertation, we
explore systems support for enabling the efficient processing and
secure sharing of sensor data using the cloud. To achieve this
goal, we adaptively use the cloud for mobile devices based on the
availability of hardware components, networks, and the state of
human workers. When appropriate, we exploit domain knowledge and
use mathematical analysis to fulfill our goals and system
requirements. ❧ We first enable compute- and data-intensive
applications on mobile devices. Some emerging applications, such as
interactive mobile perception applications, are too slow to run on
mobile devices due to both their high data-rate workload (real-time
videos) and compute-intensive algorithms used (computer
vision-based ones). Thus, we need to significantly improve the
performance by offloading part of the application components to the
cloud and parallelizing it if relevant. To achieve this goal, we
conducted a measurement study on the factors that can affect the
performance of the applications and developed a novel, lightweight,
runtime that automatically and adaptively makes offloading and
parallelism decisions for mobile interactive perception
applications. ❧ We next focus on serious privacy infringements,
such as the leakage of photos and the use of algorithmic
recognition technologies by providers, when using cloud-based photo
sharing services. Since currently we are required to expose our
data to the providers without any controls, it is impossible for
users to prevent the providers from such mining activities. On the
other hand, the providers perform useful processing on our data to
make our experience with their system better, e.g., scaling images
to support mobile devices with different form factors
appropriately. In order to simultaneously achieve both privacy
protection and processing benefits provided by the cloud, we
develop an image encryption/decryption algorithm and an associated
system that can transparently work with existing cloud-based
service providers. ❧ Third, we focus on crowd-sensing, a novel
capability that harnesses the power of crowds to collect sensor
data from a large number of mobile phone users. In such activities,
it is often challenging for users to efficiently deal with
labor-intensive sub-tasks, such as recruiting workers, giving
incentives, etc. However, existing programming systems do not
handle these concerns appropriately. Our domain-specific language
and runtime enables crowd-sensing and provides significant
automation for such tasks. Users only need to provide a high-level
description of a crowd-sensing task. Then, the runtime
automatically takes care of the rest. ❧ Fourth, when sharing large
volumes of sensor data using mobile…

▼ This study examined if using mobile technology-based activities would increase student performance in biological science courses. The study compared two groups of students in lectures and labs. Each group had about 20 students. The mobile group had mobile technology-based activities and the non-mobile group received conventional instruction. The mobile group used links to the website, or a QR Code to access the activities. The non-mobile group had handouts and worksheets over the same content. The research methodology for this study was mixed method. The study was a quasi-experimental design that used instruction method as the independent variable between two groups. The study used formative and summative assessment to compare the performance of the mobile group and non-mobile group in lecture and lab. The student in the mobile group had statistically significantly higher lab exam scores than students in the non-mobile group. Additionally, Students were surveyed about their performance expectancy and effort expectancy using mobile technology for learning, and they were asked about their self-management of learning. Analysis indicated that both groups had similar performance and effort expectancy using mobile technology for learning, but the two groups differed on self-management of learning responses to the survey. Focus groups from the mobile group and the non-mobile group were interviewed about issues related to benefits and challenges encountered learning with mobile technology-based activities.

▼ An alarming number of adolescents experience obesity and related health issues, in part because of a lack of exercise. Increased mobile technology availability can have negative effects on amount of exercise, but they can have positive effects as well. Leveraging mobile technology to encourage and motivate exercise has potential to decrease unhealthy lifestyles, especially among young people. Mobile exergaming is an emerging field that has the potential to motivate users to exercise while also having fun. However, much of the early development work on mobile exergames has been ad-hoc, with little guidance available for designers. This work seeks to identify heuristics catered for mobile exergaming. This thesis presents four mobile exergaming heuristics were identified based on recent literature and on the author's mobile exergame design and development efforts: 1) Motivational game concepts that promote physical activity; 2) Game cues that engage active users; 3) Physically and temporally appropriate game structure to encourage continual, recurring play; 4) Game play movements that are safe for the user and for the device. This thesis describes the development of the mobile exergame heuristics, along with the creation and distribution of an ExergameApp Suite comprised of three mobile exergames: Fish Out of Water, Color Hunt and Space Rayders.

▼ This thesis was commissioned by Gamespipe GmbH for the establishment of a Mobile Advertising Server which is a new dimension of their business. Double Click for publisher by Google was suggested as the first Mobile Adserver to be examined. The final objective of the commisioner was to have a Mobile Advertising Server that able to serve their customers with fast delevering, high quality and managable volume mobile traffic. The main obstacles were that the company did not have previous experiences with the mobile Adserver and lacked of technical specialist. Therefore, it was very important to test the Adserver carefully before launching. As this would be a long term testing and establishing process, a detail plan was needed. The purpose of the thesis was to write a clear project plan with different steps and analysis in order to lead the project team as well as keep them on track in a long lasting project.
Data was gathered via multiple sources both internally such as performance reports, interviews with top managemers, employee’s interviews, author’s personal observation, etc and externally such as literature resources, marketing research reports in gaming industry, High-tech magazines, academic journals, competitors interviews, professional Linkedin groups for online industry, etc. The author had been working in the commisi-oner company for one year to be able to understand its business model as well as the vision of the top management about the project.
With the team effort, the project team was formed and a clear plan had been created. It included market research information, project flow, project schedule, financial plan, risk plan and communication plan. Until July 2014, the project already had some initial re-sults by launching two appications in Google Play store. It will continue running until May 2015.
The thesis was reserved for not only the use of the commisioner but also any Technology start-up in the online application industry. It could be used as a guideline for a low cost and time saving solution by using Double Click for Publisher instead of developing their own Advertising Servers for their businesses.

▼ The users of mobile devices increasingly use networked services to address their information needs. Questions asked by mobile users are strongly influenced by context factors, such as location and user activity. However in research which has empirically documented the link between mobile information needs and context factors, information about expected answers is scant. Therefore, the goal of this study is to explore the context factors which influence the mobile information needs and the answers expected by mobile users. The results, are obtained by analysing information from paper diaries and digital diaries. This project involved a user study, comprising two different types of studies concerning a paper diary and a digital diary. The analysis of both the paper diary and the digital diary was conducted through grounded theory and taxonomy of information needs. our results indicate a relationship between mobile information needs and context factors and expected answers. Our study explored this relationship between mobile information needs and context factors, and provides a better understanding of the expected answers related to mobile information needs.

▼ Device heterogeneity and the diversity in user preferences are challenges, which must be addressed in order to achieve effective information communication in a mobile computing environment. Many model based approaches for the generation of user interfaces have been proposed. These approaches were aimed at achieving effective information communication in a mobile computing environment. Unfortunately, current model based approaches do not support user participation in interface adaptation. Hence, user interfaces are adapted for and on behalf of users, leaving users with inappropriate interfaces. There is therefore a need for an approach that allows direct user participation in interface adaptation. Such an approach must be responsive to changes in user needs and preferences. This work therefore proposes a Polymorphic Logical Description (PLD) method for automatic generation of multi-target user interfaces. The PLD method consists of user preference aware models, which are created at design time. Interface artifacts are considered in the PLD as methods with polymorphic attributes in a bid to address the diversities experienced in a mobile computing environment. An interface artifact is dynamically selected for inclusion on an interface based on the context information of a requesting user and intrinsic characteristics of a device. Our approach is enabled by a support toolkit, named Custom-MADE (CoMADE) for automatic interface generation. The evaluation result of CoMADE shows that it achieves a high degree of user participation during interface generation, flexibility, dynamism, ease of application extensibility and user centeredness interfaces.

In these last few years, mobile robots have been increasingly employed for outdoor applications. Autonomous driving in these applications is a challenging issue in mobile robotics, particularly when the domain is unstructured and harsh. In addition, uneven environments are often characterized by low visibility due to poor illumination conditions and weather phenomena including fog, rain, snow and hail, or presence of dust clouds and smoke. Thus, advanced autonomous mobile systems are primarily required for an off-road robot to sense and understand its environment, while ensuring, at the same time, robustness under compromised conditions. Therefore, this thesis addresses the problem of the design, implementation and realization of an autonomous mobile robot navigating in an uneven environment. The first issue in this work deals with the environment sensing, as it is crucial for better environment modeling strategy. A study of the most important sensors used in mobile robotics is presented. So, millimetre-wave radar (MMW radar) is chosen for our application. After that, a technique for 3D uneven environment modelling that is based on data acquired from MMW radar has been proposed. The returned raw data from the MMW are stored in a database then transferred to the CAD model, and represented as objects using an algorithm. Then, the environment is rebuilt by using Non-Uniform Rational Bi-Spline (NURBS) curves to obtain the polygon mesh representing the surface of the uneven environment. NURBS curves are used for trajectory reconstruction since they have been proven to be the best parametric curves for path planning both for 2D mobile robots and 3D curve approximation. The polygonal mesh decomposition helps us to locate the different obstacles and to build the optimal path to reach the target starting from any initial position, by taking into consideration the terrain traversability. The optimal path is obtained by applying distance calculation method and speed limits. The second issue treats the problem of path tracking, where the robot has to autonomously track the planned trajectory, provided in real-time, on rapidly varying, off-road terrain. The objective is to build a controller which permits to the robot to execute the path following task. This controller generates the actions that will drive the robot straight on the path to reach the final destination. Hence, an algorithm for data extraction is proposed and the way of sending these data to the robot platform is explained. The last issue deals with the software and hardware requirement for the realization of the mobile robot platform. Our proposed study would be useful for real-world robotic applications such as intelligent navigation for motorized wheelchairs, surveillance and security purposes, in Nuclear power plants where humans are prone to harmful radiations, for planetary exploration and every where the robot is expected to encounter rough terrain

▼Mobile computing is rapidly becoming part of healthcare’s electronic landscape, helping to provide better quality of care and reduced cost. While the technology provides numerous advantages to the healthcare industry, it is not without risk. The size and portable nature of mobile computing devices present a highly vulnerable environment, which threaten the privacy and security of health information. Since these devices continually access possibly sensitive healthcare information, it is imperative that these devices are considered for security in order to meet regulatory compliance. In fact, the increase in government and industry regulation to ensure the privacy and security of health information, makes mobile security no longer just desirable, but mandatory. In addition, as healthcare becomes more aware of the need to reinforce patient confidence to gain competitive advantage, it makes mobile security desirable. Several guidelines regarding security best practices exist. Healthcare institutions are thus faced with matching the guidelines offered by best practices, with the legal and regulatory requirements. While this is a valuable question in general, this research focuses on the aspect of considering this question when considering the introduction of mobile computing into the healthcare environment. As a result, this research proposes a framework that will aid IT administrators in healthcare to ensure that privacy and security of health information is extended to mobile devices. The research uses a comparison between the best practices in ISO 17799:2005 and the regulatory requirements stipulated in HIPAA to provide a baseline for the mobile computing security model. The comparison ensures that the model meets healthcare specific industry requirement and international information security standard. In addition, the framework engages the Information Security Management System (ISMS) model based on the ISO 27000 standard. The framework, furthermore, points to existing technical security measurers associated with mobile computing. It is believed that the framework can assist in achieving mobile computing security that is compliant with the requirements in the healthcare industry

▼ The rate of mobile phone penetration in South Africa is 120% making the potential impact of, and gains from successful mobile marketing campaigns huge. This study investigates the factors affecting mobile marketing lead generation within the context of South Africa uncovering key influences of consumers' behavioural intention to take an interest in mobile marketing messages. The report builds on concepts from the theory of planned behaviour and the technology acceptance model by utilising the augmented technology acceptance model which combines concepts from both models to carry out an examination on how the various constructs affect consumers' behavioural intentions to take an interest in mobile marketing. This model considers the effects of attitude, subjective norm, perceived behavioural control, ease of use and perceived usefulness into account in trying to assess their impact on behavioural intention, which determines a consumer's behaviour. A quantitative research approach was used and data was collected across all nine provinces in South Africa via an online survey that was dispensed via text message. Structural equation modelling utilising path analysis within the software Statistica was used to analyse the data. The findings illustrate that consumers' attitudes and subjective norms determine their behavioural intention to take an interest in mobile marketing messages, while perceived usefulness and ease of use of mobile marketing were observed to influence the attitude towards mobile marketing. This study also highlights important insights for marketers to consider when launching mobile marketing campaigns.

▼ Black women of African descent face numerous challenges when it comes to the texture of their hair. These problems can range from the day-to-day management of their natural hair to the discriminatory hair policies found in schools and professional environments, to the "paralysis" they face when having to choose an appropriate hairstyle or salon to go to. This research investigates whether a mobile application, designed to empower black women by providing them with up-to-date information about their hair and related services, would be useful in addressing some of these challenges and whether they would adopt such an application. The determinants of behavioural intention to use of technology, as prescribed by the Extended Unified Theory of Acceptance and Use of Technology, were analysed to determine whether they could account for the intention to use this mobile application. A valid sample of 242 respondents was used. The results found that, although there was a high percentage of positive behavioural intention to use the mobile application, the adopted theory explained 14% of the variation of behavioural intention. Also, of the six determinants prescribed by the theory, only performance expectancy and social influence were found to be significant contributors to behavioural intention. These results show that the UTAUT2 slightly accounts for the behavioural intention. This report recommends repeating this investigation but changing the data collection method.

▼ This study sought to establish factors influencing mobile banking in Kenya: a case of Kenya
commercial bank in Garissa, it was guided by four objectives that focused on the influence of
education, age of the respondents, cost of service and security concerns on mobile banking in
Kenya Commercial bank. The study focused on eliciting information from the customers of
the KCB bank. The main instrument for data collection was the questionnaire. Data was then
analysed using descriptive statistics and presented using frequency tables using SPSS.
Through analysis the study established that Majority of respondents were educated up to
university and tertiary college levels. However, education did not influence mobile banking.
This is because everybody in the sample owned a phone, operated a bank account and had
subscribed to mobile banking. However, skills are required to be able to operate effectively
on a mobile banking platform. Like education, age did not influence mobile banking. This is
because everybody in the sample was found to own a phone, operate a bank account and
subscribed to mobile banking. It was found that the cost of mobile banking was not too high
and a sizeable number also said it was high. There need for further studies to find out why
some feel the cost is high and come up with ways of reducing it down. Majority of
respondents said there were losses due to fraudulent access of customers’ accounts due to
hacking. In order to protect customers’ accounts, there is need to employ disciplined,
qualified and well remunerated ICT in the bank and at the level of mobile provider. In past
there have incidences of bank officials colluding with fraudsters to fleece customers’
accounts. This practice should be eliminated with advent of ICT. In order to make mobile
banking popular to all, there is need to come up with better ways of protective customer
accounts. There is also need for a comprehensive ICT policy that also covers mobile banking.

▼ The spread of mobile phones across the world is one 01" the most remarkable technology stories or the past decade.
Buoyed by prepaid cards and inexpensive handsets, hundreds of millions of first-time telephone owners have made
voice calls and text messages part of their daily lives. In Kenya the first quarter of201012011 report from CCK, the
lour licensed operators had a combined subscriber base of 22 million mobile subscribers, a 9.5 per cent mobile
subscriptions growth from 20.1 million in the last quarter to 22 million subscribers. This is the highest growth that
has been recorded over the last three quarters (CCK 201 O).This growth is attributed to the continued reduction III
the cost of mobile handsets as well as the low value of prepaid calling cards,
Large chunk of mobile phone users are prepaid customer, according to CCK the prepaid subscribers whose
proportion or total subscribers reached 99%, (CCK 2010). Yet the available options of toping up air time token is
characterized with scratch card manufacturing costs, transportation costs, storage costs, control of distribution
channels, Service management, distribution links and stratification of customer according to networks. Therefore
the purpose of the study was to investigate the recharge options available for air time token with a view of
developing a self service, electronic top up prototype with an intuitive interface that is simple easy and fast way of
iopi ng up air time token.
The research adopted Structured Systems Analysis and Design Methodology (SSA DM) using Java Developrnen t
Platform An electronic top model for prepaid customers with a user friendly interface has been developed.
Air time tokens are credited to mobile devices upon payment through the interface of the electronic top up devices.
The user receives a confirmation message of toping up the mobile device. The Prototype was tested and time taken
was measured in relation to other top up options available, various graphs were plotted comparing time taken to load
air time. The study showed that electronic top method developed was faster than other available options; therefore
the technology can be adopted.
The main contribution of the study is the integration of the selfservice prototype in the provision of air time through
the use of electronic top up system as an approach towards solving problems inherent in the current available option
of toping mobile phone.

▼Mobile learning (m-learning) is a methodology of supporting learning which is spontaneous,
anywhere-anytime learning through the use of mobile technology. With the ubiquity of mobile
phones and the broad availability of advanced features similar to pes, there is sufficiently large
basis for development of education-rich applications. M-learning projects are pre-dominantly
being carried out in the developed countries. The designers of current mobile technologies do not
necessarily consider the conditions of developing countries when designing and so their products
are not always applicable in the developing world. Therefore, the evaluation frameworks used in
developed countries are not applicable in developing countries.
Using survey and case study methodology, this research developed and tested a Mobile Learning
Impact Measurement Framework (MLIMF) to address the problem. Using standards from
training and development community, the researcher developed dimensions to evaluate mlearning.
The dimensions were then applied to a sample of thirty eight (38) participants who have
sued or are using m-learning systems. This was in order to assess the feasibility of the framework
and the dimensions in evaluating m-learning. To develop the MLIMF, three hypotheses were
tested. The data available for this study was limited to a sample of thirty eight (38) participants
and two m-learning systems allowing only a broad analysis. However, the research undertaken
proved the value of the framework as a tool for research and confirmed the validity of the
framework design.
Analysis of the results indicates that learner and environmental characteristics impact on the
success of m-learning. The results have indicated that learner attitudes, motivations, experience,
existing knowledge and skills and performance are significant to the success of m-learning
systems. We also established that the application characteristics including content adaptability,
cost, reliability and relevance of the materials are important aspects to consider.
The framework aims at guiding policy in development of applications that can enable learners in
developing countries obtain access to and use learning, through the use of mobile phones. It
provides a competency set of novel guidelines to be followed when developing mobile learning
systems and also to evaluate existing m-learning environments, products and services.

▼Mobile Internet has emerged as a tool that is changing the lives of many consumers
especially in the developing countries by enabling them to access information. The objective
of this research was to determine the extent to which Kenyan university students accept
Mobile Internet, to identify the mobile platforms and data plans used, to identify and qualify
the constructs that do affect adoption of Mobile Internet and to identify the services accessed
by users of mobile internet.
Most research work on Mobile internet adoption is structured on Technology Acceptance
Model (TAM). This research however included additional constructs to TAM and attempt to
justify their effect on Mobile Internet adoption among university students in Kenya.
The study found that majority of the respondents indicated that they were using ordinary
phones and smart phones to access Mobile Internet. The respondents accessed different
services on their mobile devices like Social networking, checking the news, accessing
research materials and accessing e-mails. Most of the respondents preferred pre-paid data
bundles.
The study found that consumer's perceived ease of use had a positive impact on intention to
use M-internet. It was also found that perceived usefulness had a positive impact on
consumer's intention to use M-internet. The study also revealed that consumer's attitude
toward M-internet had a positive impact on his/her intention to use M-internet. Consumer's
perception of playfulness was found to have positive impact on intention to use M-internet.
Internet experience was also shown to have a positive impact on a consumer's intention to
use M-internet. Consumer's perception of service cost was shown to have an impact on
intention to use M-internet. System quality was shown to have an impact on a consumer's
intention to use M-internet. A consumer's perception of content quality also was shown to
have an impact on intention to use M~internet. All these results were consistent with previous
studies focusing on TAM framework as well as the studies on the additional Constructs.

▼ One of the recent developments in mobile wireless applications is the introduction of
mobile commerce using mobile devices such as PDAs, cellular phones and notebook pes.
Some of the applications of mobile commerce include Funds Transfer, m-banking, rnbilling
and m-shopping,
The main driving force for the rapid acceptance of mobile devices in business sector is their
capability to provide or get services at any time and any place where there is network
coverage. Moreover rn-cornrnerce has proved to be a cheaper and efficient alternative to
costly traditional commercial services particularly in developing countries such as Kenya.
However as the popularity of these services mcrease, there is great concern on loss of
confidential data transmitted over the insecure wireless network. In this research, we
analyzed existing frameworks for secure mobile funds transfer services in order to adopt or
propose a suitable framework that will be used as a guide for deployment and assessment of
mobile wireless money transfer services. The three core areas that guided our research are:•
Transmission security for electronic money (e-rnoney) in cellular wireless networks.
• Security in SIM-based mobile money transfer applications.
• Policies and regulatory framework governing mobile money transfer services.
To validate the framework, the research methodology employed in this research was mainly
survey. Through stratified random sampling on clustered regions, our sample was drawn
from mobile money transfer subscribers, dealers/agents of Safaricom's M-Pesa and Zain's
Zap mobile money transfer services and the two service providers i.e. Safari com and Zaino
The outcome of our research findings is a validated framework that will serve as a blue
print for the deployment and assessment of m-payment services in the developing countries
where approximately 80% are unbanked.

▼ The uptake of mobile phone technology in Kenya has been unprecedented. Of vital
significance is the rapid absorption of mobile money technology/services.. In an effort to
gauge the effect/ implications of this mobile phone phenomena to the NGO sector
financial management efforts, this study brought to the light the available evidence on the
effect of the mobile money uptake on financial performance of NGO
’
s in Kenya.
Explo
ratory research design was adopted to investigate the effect of MMU on the
financial performance of NGO
’
s in Kenya and to investigate this relationship,
quantitative research approach was employed. To ensure a more complete approach to
empirical research,
longitudinal data were collected in a sequence so as to track the
magnitude of change that would have taken place. The instruments used included the use
of structured questionnaires and interviews. Interviews were conducted to give in

depth
information wh
ich was omitted by the questionnaire. The survey was administered on 30
respondents out of 50 members of the national and international NGO, s in Kenya. Data
was subjected to exploratory analysis through descriptive and correlation procedures.
The result o
f the study indicates very promising positive effect of MMU on financial
performance of NGO
’
s that have adopted mobile money in their financial performance
and indeed significant positive effect on, improved customer engagement and
satisfaction, compliance with donor regulations, efficiency and effectiveness and most
importantly reduced fiscal risk status among others.
In conclusion the study brings out the needed evidence that indeed MMU is the way to go
if NGO
’
s have to improve on
their financial performance and for the future good and as
vital addition to the current government policies in the area of MMT, donors should
formulate key policy to require their funds recipients adopt MMU as the appropriate way
of undertakings funds di
sbursements.

▼Mobile banking has been considered to be one of the most value-added and important
mobile services currently available. Considering the fact that the penetration of this
technology is undefined well, particularly in developing country, this study sought find
out the influence of perceived mobile banking risks on the benefits derived from usage.
The research did an empirical study in Nairobi investigating the impacts of risks on
mobile banking and the influence it possess to financial inclusion and sought to find out
the risks m-banking users are exposed to. Data was collected from 357 respondents and
the findings identified some eminent risks transactions; withdrawal via ATM, high value
cash deposits/ withdrawals and customer to customer transactions. The study found out
that there is a direct relationship between risks and the impacts on financial inclusion.
The uptake of Mpesa, agent‟s growth and turnover of funds were growing on a steady
state since the service started.
The uptake of mobile phones in Kenya has been unprecedented. The most significance is
rapid absorption of mobile based banking services. This trend of continued reliance on
mobile devices to execute monetary transactions is steadily gaining momentum. In an
effort to gauge the implications of these mobile phone phenomena, this study set out to
bring to light the critical risks and impacts arising from the emergent mobile technology
innovations on financial inclusion. Two risks were identified; fraudulent calls and fake
text messages. This paper is structured to offer insights into the current state of mobile
phone banking service as well as a review of emerging risks and impacts on financial
inclusion. Illuminative cases are also featured to drive home the fundamental paradigms
of concern in this study. The paper is based on a study conducted on existing mobile
banking service- mpesa in Kenya.
The study cited security measures to safeguard customer as strict adherence to safaricom
vetting procedures on transacting and educating customers on keeping the mpesa pin
confidential.

▼ The advance of mobile phone devices and wireless communication have dramatically change the way individuals do for their personal lives and businesses. Nowadays, people can not only talk with their peers located at different places, they can also get the desired information ubiquitously. Business strategies that are based on simple mobile phones have to be adapted to a complex mobile business ecosystem.
The mobile phone market in Guatemala has almost saturated, and the mobile operators have to come up with creative ideas to increase their revenues. This thesis explores what the userâs intentions toward mobile services in Guatemala. Understanding usersâ intension will allow entrepreneurs to create new business strategies that would fill an existing void that exists on the Guatemalan mobile market.

▼ The number of mobile devices is growing very fast. Smart phones and tablets are, step by step, replacing desktops and laptops as the primary method of computing in daily life. Along with the rapid evolution of mobile devices, the applications on them are undergoing fast transformation. We can see many improvements in traditional applications (messaging, calling, etc.) like multimedia text messages, video calls, voice over IP and so forth. However, the Contacts application has not changed much while it has many potentials. In this thesis, we propose a new model which improves the Contacts application by introducing three novel capabilities: searching for contacts by their miscellaneous information, retaining knowledge of contacts via a tags system, and establishing a Personal Social Network which consists of the relationships between the contacts. By introducing these capabilities, the model helps its users to accomplish new tasks which are not currently handled by modern Contacts applications. Furthermore, the model is implemented and become a fully functional prototype on iOS and Android. The prototype is then evaluated in a user study and a system performance test. The studies yield positive results which indicate that the three new capabilities are valuable and should be included in today’s Contacts applications.

▼ Technology offers new possibilities to provide effective teaching and learning. One of the
most recent technologies that has ignited considerable interest by educators is mobile
technology. Mobile technology has been quickly adopted in everyday life, and it is common
for most people to have, and carry, a mobile device with them at all times. In addition these
mobile devices are becoming more and more powerful and taking over tasks that would
normally be done on traditional PCs or laptops (Dawabi, Wessner, & Neuhold, 2004).
Researchers have started to explore the way mobile technology can be harnessed in the
educational arena (see for example Attewell & Gustafsson, 2002; Cobcroft, Towers, Smith,
& Bruns, 2006; Seppälä & Alamäki, 2003; Traxler, 2009; Zawacki-Richter, Brown, & Delport,
2009; Zeng & Luyegu, 2011). Despite the interest, little is known about the factors that will
impact student and educator adoption of mobile learning. Current studies into mobile
learning are mainly small scale trials and pilots with most focussing on student adoption.
Factors that affect the mobile learning adoption by educators seem to have been largely
ignored.
To address this gap in the literature, the present study has developed two models of
student and educator adoption of mobile learning. The models posited that the perceived
ease of use and usefulness of mobile technology would mediate the relationship between
self-efficacy beliefs, motivation and level of self-direction of students and the intention of
students and educators to adopt mobile learning.
A total of 446 students from three tertiary institutes and 196 educators from all New
Zealand completed a survey that identified their learning and teaching-related beliefs and
attitudes, their intentions to adopt mobile learning, and their perceptions of using mobile
technology to support their learning and teaching.
The study found that educators and students are influenced by different factors to adopt
mobile learning. Specifically, it found that the self-efficacy beliefs, motivation and selfdirectedness
(students) had varying degrees of influence on ease of use and usefulness
perceptions of mobile learning, and overall intention to adopt it. The study also found
evidence to suggest that these factors may differ between students of different ages,
genders and institute types they attend.
The study also provides recommendations to educators, researchers, learning designers and
institutes who wish to implement mobile learning into their curriculum to accommodate
and encourage adoption.

▼ Autonomous robots in real-world environments face a
number of challenges even to accomplish apparently simple tasks
like moving to a given location. We present four realistic
scenarios in which robot navigation takes into account partial
information, hierarchical structures, and multiple objectives. We
start by discussing navigation in indoor environments shared with
people, where routes are characterized by effort, risk, and social
impact. Next, we improve navigation by computing optimal
trajectories and implementing human-friendly local navigation
behaviors. Finally, we move to outdoor environments, where robots
rely on uncertain traversability estimations and need to account
for the risk of getting stuck or having to change
route.

An opportunistic model of mobile computing is presently emerging in which users can fully benefit from their personal computing environment wherever they are without having to carry "heavy-weight" mobile systems with them. The transition to this model can be seen as part of the pervasive computing vision, being catalyzed by the near ubiquity of powerful smart phones, the increasing availability of local PC hardware, and recent trends in virtualization and cloud computing. The fate of the opportunistic mobile computing model will be essentially decided by the performance, availability, and security of data access relative to alternative solutions. Mobile users require safe and efficient access to their data from whatever PC or device they are currently using, wherever they may be. These requirements expose several new challenges to the performance, availability, and security of user data access under opportunistic mobile computing conditions. In this dissertation, we identify challenges to user data access within the opportunistic mobile computing model, present novel approaches to address them, and demonstrate the effectiveness of these approaches through extensive experimentation. To improve the performance of data access for opportunistic mobile computing, we introduce the concept of safe borrowing of local storage, which we prototyped as the TransPart system. To improve the availability of data access for opportunistic mobile computing, we introduce the concept of a self-cleaning portable cache, which we prototyped as the Horatio system. To improve the security of remote data access for opportunistic mobile computing, we introduce the Working Set-Based Access Control (WSBAC) scheme, which applies the concept of the working set to distributed file system access control. The main conclusion of our research is that opportunistic mobile computing can be realized in a safe and efficient manner for mobile users. Given the ad-hoc nature of opportunistic mobile computing, it is likely that the challenges identified in this dissertation will continue to exist into the foreseeable future. Fortunately, as our research shows, they can be addressed using nascent technologies and applying our concepts without violating the basic tenet of opportunistic mobile computing, namely to minimize the burden of what hardware users must carry.

▼ Smart phones and other mobile technologies can be used
to collect and display physiological information from subjects in
various environments – clinical or otherwise. This thesis
highlights software app reference designs that allow a smart phone
to receive, process, and display biomedical data. Two research
projects, described below and in the thesis body, guided this
development. Android Studio was chosen to develop the phone
application, after exploring multiple development options
(including a cross-platform development tool), because it reduced
the development time and the number of required programming
languages.
The first project, supported by the Kansas State
University Johnson Cancer Research Center (JCRC), required a mobile
device software application that could determine the hemoglobin
level of a blood sample based on the most prevalent color in an
image acquired by a phone camera, where the image is the result of
a chemical reaction between the blood sample and a reagent. To
calculate the hemoglobin level, a circular region of interest is
identified from within the original image using image processing,
and color information from that region of interest is input to a
model that provides the hemoglobin level. The algorithm to identify
the region of interest is promising but needs additional
development to work properly at different image resolutions. The
associated model also needs additional work, as described in the
text.
The second project, in collaboration with Heartspring,
Wichita, KS, required a mobile application to display information
from a sensor bed used to gather nighttime physiological data from
severely disabled autistic children. In this case, a local data
server broadcasts these data over a wireless network. The phone
application gathers information about the bed over this wireless
network and displays these data in user-friendly manner. This
approach works well when sending basic information but experiences
challenges when sending images.
Future work for both project
applications includes error handling and user interface
improvements. For the JCRC application, a better way to account for
image resolution changes needs to be developed, in addition to a
means to determine whether the region of interest is valid. For the
Heartspring application, future work should include improving image
transmissions.
